Description

本発明は、扉体(特に開き戸)の反り矯正構造と、その反り矯正構造を用いた扉ユニットに関する。   The present invention relates to a warp correction structure of a door body (particularly a hinged door) and a door unit using the warp correction structure.

例えば、部屋への出入り用扉等の開き戸を、矩形状の開口を構成する固定枠等の扉取付部に対して、扉の厚さ(扉正面に対峙する作業者の前後)方向、幅(同じく左右)方向及び高さ(同じく上下)方向へそれぞれ位置調整(隙間調整)可能とするための蝶番が一般に知られている。これによって、開き戸を固定枠に取付施工する際に、また、使用によって開き戸や固定枠が変形したり開き戸の取付位置がずれたりしたときにも、開き戸をスムーズに開閉できるように開き戸と固定枠との3方向(厚さ方向、幅方向及び高さ方向)の相互間隔(隙間)をそれぞれ所定範囲内に調整できる(特許文献1参照)。   For example, for a door such as a door for entering and exiting a room, with respect to a door mounting portion such as a fixed frame that forms a rectangular opening, the thickness of the door (front and back of the worker facing the front of the door), width ( A hinge for enabling position adjustment (gap adjustment) in each of the same (left and right) direction and height (also up and down) direction is generally known. As a result, when installing the hinged door on the fixed frame, and when the hinged door or the fixed frame is deformed or the installation position of the hinged door is shifted due to use, the hinged door and the fixed frame can be opened and closed smoothly. Can be adjusted within a predetermined range (see Patent Document 1).

一方、このような開き戸では、取付施工時、長年使用後を問わず、製造誤差、自重、内外の温度差等により厚さ方向への反りを生じやすく、特に、大型で重厚な木製ドアで顕著に現われる。したがって、開き戸の上記3方向の位置調整が適切に行われていても、厚さ方向への反りの発生によって建て付けが悪くなったり、見栄えが悪くなったりすることがある。そこで、開き戸においてこのような厚さ方向への反りを矯正するために、縦枠(固定枠)の中間部に外側へ突出する係止部(枠側矯正部材)を設けるとともに、障子(開き戸)の枢着側縦框に係止部と係合する凹部(障子側矯正部材)を設けることが開示されている(特許文献2参照)。   On the other hand, such hinged doors are prone to warp in the thickness direction due to manufacturing errors, their own weight, internal and external temperature differences, etc., regardless of whether they have been used for many years after installation, especially for large and heavy wooden doors. Appear in. Therefore, even if the position adjustment of the above three directions of the hinged door is appropriately performed, the building may be deteriorated or the appearance may be deteriorated due to the warp in the thickness direction. Therefore, in order to correct such warpage in the thickness direction in the hinged door, a locking portion (frame-side correction member) protruding outward is provided at the intermediate portion of the vertical frame (fixed frame), and a shoji (folding door) It is disclosed that a concave portion (a shoji side correction member) that engages with a locking portion is provided in the pivot attachment side shaft (see Patent Document 2).

特許第3798416号公報Japanese Patent No. 3798416 特許第2726013号公報Japanese Patent No. 2726013

特許文献2のような反り矯正構造によれば、係止部と凹部とにそれぞれ形成するR面によって、内外の温度差により生じる厚さ方向への反りを矯正することができる。しかし、特許文献2の反り矯正構造では、係止部と凹部とが縦枠と縦框とにそれぞれ固定された状態で障子が開閉されるので、使用により厚さ方向への反りが拡大すると、係止部と凹部とが係合できなくなったり、係止部と凹部との係合が解除できなくなったりして、反り矯正構造が機能しなくなるおそれがある。また、取付施工時等に、例えば障子を上記厚さ方向や幅方向に位置調整(隙間調整)した場合にも、係止部と凹部とが係合できなくなったり、係止部と凹部との係合が解除できなくなったりして、反り矯正構造が機能しなくなるおそれがある。したがって、使用条件によっては比較的短期間でも、障子が開放位置から閉鎖位置に移行できなくなったり、逆に閉鎖位置から開放位置に移行できなくなったりするために、枠から障子を取り外し、各矯正部材(係止部と凹部)を交換しなければならなくなる。   According to the warp correction structure as in Patent Document 2, warpage in the thickness direction caused by a temperature difference between the inside and the outside can be corrected by the R surfaces formed respectively in the locking portion and the recess. However, in the warp correction structure of Patent Document 2, since the shoji is opened and closed in a state in which the locking portion and the concave portion are fixed to the vertical frame and the vertical hook, respectively, when warping in the thickness direction is expanded by use, There is a possibility that the locking portion and the recess cannot be engaged or the engagement between the locking portion and the recess cannot be released, and the warp correction structure does not function. Also, for example, when adjusting the position of the shoji in the thickness direction or width direction (gap adjustment) at the time of installation or the like, the engaging portion and the recessed portion cannot be engaged, or the engaging portion and the recessed portion There is a possibility that the warp correction structure may not function because the engagement cannot be released. Therefore, depending on the conditions of use, the shoji cannot be moved from the open position to the closed position even in a relatively short period of time. It will be necessary to exchange (the locking portion and the concave portion).

本発明の課題は、永久磁石を用いた簡素な構成によって開き戸等の扉体に生じる厚さ方向の反りを容易に矯正することができ、しかもそのような反り矯正機能を長期間にわたり安定して発揮することのできる、扉体の反り矯正構造及びその反り矯正構造を用いた扉ユニットを提供することにある。   An object of the present invention is to easily correct a warp in a thickness direction generated in a door body such as a hinged door with a simple configuration using a permanent magnet, and to stably perform such a warp correction function over a long period of time. It is providing the door unit using the curvature correction structure of the door body which can be exhibited, and the curvature correction structure.

課題を解決するための手段及び発明の効果Means for Solving the Problems and Effects of the Invention

上記課題を解決するために、本発明の扉体の反り矯正構造は、
矩形状の開口を構成する固定枠等の扉取付部に対して、その開口を閉鎖する閉鎖位置と開放する開放位置との間で回動軸線周りに開閉可能な開き戸等の扉体が、その厚さ方向に反るのを矯正するための矯正構造であって、
前記扉取付部と扉体とのうちいずれか一方側に取り付けられ、前記扉体が前記閉鎖位置に移行する際に突出し前記開放位置に移行する際に退入することにより直線的に移動する移動体と、
前記扉取付部と扉体とのうち他方側に固定され、突出状態の移動体(の先端部)を挿入保持するための凹部を有する保持体と、を備え、
それら移動体と保持体とのうちいずれか一方は、所定の極性に着磁された永久磁石を含むとともに、前記移動体と保持体とのうち他方は、前記永久磁石の磁界から磁気誘導作用を受けて磁化することによりその永久磁石に吸着可能となる被吸着部を含み、
前記扉体が前記開放位置から閉鎖位置に移行するとき、前記被吸着部は、前記永久磁石との接近につれてその永久磁石による磁気誘導作用の度合いが強まることによって、当該永久磁石に(直接又は他部材を介して間接的に)吸着する一方、
前記扉体が前記閉鎖位置から開放位置に移行するとき、前記被吸着部は、前記永久磁石からの離間につれてその永久磁石による磁気誘導作用の度合いが弱まることによって、当該永久磁石から離反することを特徴とする。
In order to solve the above problems, the warp correction structure of the door body of the present invention is:
A door body such as a hinged door that can be opened and closed around a rotation axis between a closed position that closes the opening and an open position that opens the door mounting portion such as a fixed frame that forms a rectangular opening. A straightening structure for correcting warping in the thickness direction,
A movement that is attached to either one of the door mounting portion and the door body and moves linearly by protruding when the door body moves to the closed position and retreating when the door body moves to the open position. Body,
A holding body that is fixed to the other side of the door mounting portion and the door body and has a recess for inserting and holding the projecting moving body (the front end portion thereof),
One of the moving body and the holding body includes a permanent magnet magnetized to a predetermined polarity, and the other of the moving body and the holding body has a magnetic induction action from the magnetic field of the permanent magnet. Including an attracted part that can be attracted to the permanent magnet by receiving and magnetizing,
When the door body moves from the open position to the closed position, the attracted portion increases the degree of magnetic induction by the permanent magnet as it approaches the permanent magnet (directly or otherwise). While adsorbing indirectly (through the member)
When the door body moves from the closed position to the open position, the attracted portion is separated from the permanent magnet by decreasing the degree of magnetic induction by the permanent magnet as it is separated from the permanent magnet. Features.

このような反り矯正構造では、移動体(例えばシャフト)と保持体(例えばケーシング)とのうちいずれか一方は永久磁石(例えばネオジム磁石)を含み、他方は永久磁石に吸着可能な被吸着部(例えば鉄棒)を含む。このような簡素な構成であっても、扉体(例えば開き戸)が開放位置から閉鎖位置に移行するにつれて、被吸着部が突出し永久磁石に(直接又は他部材を介して間接的に)吸着する一方で、扉体が閉鎖位置から開放位置に移行するにつれて、被吸着部が退入し永久磁石から離反する。したがって、扉体の閉鎖位置への移動(回動)毎に永久磁石が移動体を突出させて被吸着部を吸着するので、使用に伴って扉体の厚さ方向への反りが拡大傾向になっても、永久磁石の吸着力により反りの矯正を安定して行える。また、取付施工時等に、扉取付部(例えば固定枠)に対して扉体を厚さ方向や幅方向に位置調整(隙間調整)した場合にも、永久磁石の吸着力により反りの矯正を安定して行える。しかも、扉体の閉・開操作に応じて永久磁石により移動体を移動させるだけで反り矯正構造の作動・作動解除の切換が行えるので、反り矯正機能を長期間にわたり安定して発揮することができる。   In such a warp correction structure, either one of the moving body (for example, the shaft) and the holding body (for example, the casing) includes a permanent magnet (for example, a neodymium magnet), and the other is an attracted portion that can be attracted to the permanent magnet ( For example, a horizontal bar). Even in such a simple configuration, as the door body (for example, a hinged door) moves from the open position to the closed position, the attracted portion protrudes and is attracted to the permanent magnet (directly or indirectly via another member). On the other hand, as the door body moves from the closed position to the open position, the attracted part retreats and separates from the permanent magnet. Therefore, each time the door body is moved (rotated) to the closed position, the permanent magnet causes the moving body to protrude and attract the attracted portion, so that the warp in the thickness direction of the door body tends to increase with use. Even if it becomes, the correction of curvature can be stably performed by the attractive force of the permanent magnet. Also, when the door body is adjusted in the thickness direction or width direction (gap adjustment) with respect to the door mounting part (for example, a fixed frame) at the time of installation, etc., the warp is corrected by the attractive force of the permanent magnet. It can be done stably. In addition, the warp correction structure can be switched between activation and deactivation simply by moving the movable body with a permanent magnet in accordance with the closing / opening operation of the door body, so that the warp correction function can be exhibited stably over a long period of time. it can.

さらに、扉体(開き戸)が部屋への出入り用ドア等の場合には、扉取付部(固定枠)に形成される「矩形状開口」は、高さ(上下)方向が長辺、幅(左右)方向が短辺の出入口を構成することになる。ところで、永久磁石や移動体(被吸着部)は、一般に強磁性体で構成されている。そして、永久磁石には、ネオジム磁石、フェライト磁石、アルニコ磁石、KS鋼、MS鋼等の硬磁性材料が用いられ、一方、移動体(被吸着部)には、鉄、ケイ素鋼、パーマロイ等の軟磁性材料が用いられる。   Furthermore, when the door body (folding door) is a door for entering and exiting a room, the “rectangular opening” formed in the door mounting portion (fixed frame) has a long side in the height (vertical) direction and a width ( The left / right direction forms a short side entrance. By the way, a permanent magnet and a moving body (adsorbed portion) are generally made of a ferromagnetic material.

Moreover, in order to solve the said subject, the curvature correction structure of the door body of this invention is a case of said (A) as a concrete aspect, and in the case of said (a),
A door body such as a hinged door that can be opened and closed around a rotation axis between a closed position that closes the opening and an open position that opens the door mounting portion such as a fixed frame that forms a rectangular opening. A straightening structure for correcting warping in the thickness direction,
It is attached to the door body on one side of the door mounting portion and the door body, and protrudes when the door body moves to the closed position, and moves linearly by retreating when the door body moves to the open position. A moving object,
A holding body that is fixed to the door mounting section on the other side of the door mounting section and the door body and has a recess for inserting and holding the projecting moving body (the front end section thereof);
One holding body of the moving body and the holding body includes a permanent magnet magnetized to a predetermined polarity, and the other moving body of the moving body and the holding body is (a tip portion in the moving direction). A) a portion to be attracted that can be attracted to the permanent magnet by being magnetized by receiving a magnetic induction effect from the magnetic field of the permanent magnet;
When the door body moves from the open position to the closed position, the attracted portion increases the degree of magnetic induction by the permanent magnet as it approaches the permanent magnet (directly or otherwise). While adsorbing indirectly (through the member)
When the door body moves from the closed position to the open position, the attracted portion is separated from the permanent magnet by decreasing the degree of magnetic induction by the permanent magnet as it is separated from the permanent magnet. Features.

上記反り矯正構造では、保持体(例えばケーシング)は永久磁石(例えばネオジム磁石)を含み、移動体(例えばシャフト)は永久磁石に吸着可能な被吸着部(例えばシャフト先端部の鉄棒)を含む。このような簡素な構成においても、扉体(例えば開き戸)が開放位置から閉鎖位置に移行するにつれて、被吸着部が突出し永久磁石に(直接又は他部材を介して間接的に)吸着する一方で、扉体が閉鎖位置から開放位置に移行するにつれて、被吸着部が退入し永久磁石から離反する。したがって、扉体の閉鎖位置への移動(回動)毎に永久磁石が移動体を突出させて被吸着部を吸着するので、使用に伴って扉体の厚さ方向への反りが拡大傾向になっても、永久磁石の吸着力により反りの矯正を安定して行える。また、取付施工時等に、扉取付部(例えば固定枠)に対して扉体を厚さ方向や幅方向に位置調整(隙間調整)した場合にも、永久磁石の吸着力により反りの矯正を安定して行える。しかも、扉体の閉・開操作に応じて永久磁石により移動体を移動させるだけで反り矯正構造の作動・作動解除の切換が行えるので、反り矯正機能を長期間にわたり安定して発揮することができる。   In the warp correction structure, the holding body (for example, the casing) includes a permanent magnet (for example, a neodymium magnet), and the moving body (for example, the shaft) includes a portion to be attracted (for example, an iron rod at the tip of the shaft) that can be attracted to the permanent magnet. Even in such a simple configuration, as the door body (for example, a hinged door) moves from the open position to the closed position, the attracted portion protrudes and is attracted to the permanent magnet (directly or indirectly via another member). As the door body moves from the closed position to the open position, the attracted portion retreats and moves away from the permanent magnet. Therefore, each time the door body is moved (rotated) to the closed position, the permanent magnet causes the moving body to protrude and attract the attracted portion, so that the warp in the thickness direction of the door body tends to increase with use. Even if it becomes, the correction of curvature can be stably performed by the attractive force of the permanent magnet. Also, when the door body is adjusted in the thickness direction or width direction (gap adjustment) with respect to the door mounting part (for example, a fixed frame) at the time of installation, etc., the warp is corrected by the attractive force of the permanent magnet. It can be done stably. In addition, the warp correction structure can be switched between activation and deactivation simply by moving the movable body with a permanent magnet in accordance with the closing / opening operation of the door body, so that the warp correction function can be exhibited stably over a long period of time. it can.

そして、これらの反り矯正構造において、移動体には、その移動体を常時退入状態に付勢するための付勢手段(例えば圧縮コイルばね)が設けられていることが望ましい。   In these warp correction structures, it is desirable that the moving body is provided with urging means (for example, a compression coil spring) for urging the moving body in a retreating state at all times.

このような付勢手段を備えることによって、
扉体が開放位置から閉鎖位置に移行するとき、被吸着部は、永久磁石との接近につれてその永久磁石による磁気誘導作用の度合いが強まることによって、永久磁石への吸着力が付勢手段の付勢力を上回り、永久磁石に(直接又は他部材を介して間接的に)吸着する一方、
扉体が閉鎖位置から開放位置に移行するとき、被吸着部は前記永久磁石からの離間につれてその永久磁石による磁気誘導作用の度合いが弱まることによって、永久磁石への吸着力が付勢手段の付勢力を下回り、永久磁石から離反することができる。
By providing such a biasing means,
When the door body moves from the open position to the closed position, the attracted portion applies the biasing force to the permanent magnet by increasing the degree of magnetic induction by the permanent magnet as it approaches the permanent magnet. While surpassing the force and adsorbing to the permanent magnet (directly or indirectly through other members)
When the door body moves from the closed position to the open position, the attracting force of the attracted part is applied to the permanent magnet by the degree of the magnetic induction action by the permanent magnet as the distance from the permanent magnet decreases. It is less than power and can be separated from the permanent magnet.

ところで、これらの反り矯正構造において、被吸着部(例えばシャフトの先端部)は、永久磁石と閉鎖位置において互いに対向することとなる対向部位での極性を異ならせることによって、その永久磁石との間の磁気作用に基づき吸着力を増大させるための補助永久磁石(例えばネオジム磁石)を含むことができる。   By the way, in these warp correction structures, the portion to be attracted (for example, the tip of the shaft) differs between the permanent magnet and the permanent magnet by differentiating the polarities at the facing portions that face each other in the closed position. An auxiliary permanent magnet (for example, a neodymium magnet) for increasing the attraction force based on the magnetic action can be included.

これによって、移動体には、永久磁石の磁気誘導作用に基づく永久磁石と被吸着部との間の吸着力に加えて、永久磁石と補助永久磁石との間の磁気作用に基づく吸着力が作用することになり、移動体(被吸着部)が円滑にかつ安定して突出移動できる。なお、永久磁石に用いられる硬磁性材料から選択して補助永久磁石にも適用することができるので、永久磁石の大きさ(径や厚み)を小さくし、全体構造の小型化を図ることも容易となる。   As a result, an attractive force based on the magnetic action between the permanent magnet and the auxiliary permanent magnet acts on the moving body in addition to the attractive force between the permanent magnet and the attracted part based on the magnetic induction action of the permanent magnet. As a result, the moving body (adsorbed portion) can move smoothly and stably. Since it can be selected from hard magnetic materials used for permanent magnets and applied to auxiliary permanent magnets, it is easy to reduce the size (diameter and thickness) of the permanent magnets and downsize the entire structure. It becomes.

さらに、移動体は、移動方向を長手方向とする軸状部材で形成され、かつ保持体との対向側の先端部(例えば被吸着部)が先端に向かうにつれて連続的に縮径する縮径部に構成される一方、
保持体の凹部には、扉体の閉鎖状態において凹部に対する移動体の挿入方向前方側ほど移動体に近づく案内部が配置され、
扉体が開放位置から閉鎖位置に移行するとき、移動体の縮径部は、案内部で当接案内されて保持体の凹部に挿入保持されることが望ましい。
Furthermore, the moving body is formed of a shaft-like member whose moving direction is the longitudinal direction, and the diameter-reducing portion that continuously decreases in diameter as the front end portion (for example, the attracted portion) facing the holding body moves toward the front end. While configured into
In the recessed portion of the holding body, a guide portion that is closer to the moving body is arranged closer to the front side in the insertion direction of the moving body with respect to the recessed portion in the closed state of the door body ,
When the door body moves from the open position to the closed position, it is desirable that the reduced diameter portion of the moving body is abutted and guided by the guide portion and inserted and held in the concave portion of the holding body.

このような案内部を保持体の凹部に配置することによって、扉体の閉鎖位置への移行時に、縮径部を早めに案内部に当接させ、移動体を保持体の凹部へ誘い込み案内することができる。したがって、扉体の厚さ方向への反りが拡大傾向になった場合や、扉取付部に対して扉体を厚さ方向に位置調整(隙間調整)した場合にも、永久磁石が被吸着部を安定して吸着でき、扉体の反りを矯正することができる。 By disposing such a guide portion in the concave portion of the holding body , the reduced diameter portion is brought into contact with the guide portion early when the door body is moved to the closed position, and the movable body is guided to the concave portion of the holding body. be able to. Therefore, even when the warpage of the door body in the thickness direction tends to expand, or when the door body is adjusted in the thickness direction (gap adjustment) with respect to the door mounting part, the permanent magnet is Can be stably adsorbed and the warping of the door body can be corrected.

具体的には、案内部は、凹部に対する移動体の挿入方向下手側ほど移動体に近づく(漸近する)ように(湾曲)形成され、縮径部が当接したとき、移動体を挿入方向に引き寄せつつ保持体の凹部へ誘い込み案内する。   Specifically, the guide portion is formed (curved) so as to approach (asymptotically) approach the moving body toward the lower side of the moving body in the insertion direction with respect to the recess, and when the reduced diameter portion comes into contact, the moving body moves in the insertion direction. Guide and guide to the concave portion of the holding body while pulling.

なお、閉鎖位置において、移動体は扉取付部又は扉体の取付面に対して直交状に配置されていると、永久磁石による被吸着部の吸着が安定する。また、凹部に対する移動体の挿入方向に直交する面において、永久磁石の最大投影面積が移動体の最大投影面積よりも大きく形成されていると、扉体の厚さ方向への反りが拡大傾向になった場合や、扉取付部に対して扉体を厚さ方向に位置調整(隙間調整)した場合にも、永久磁石が被吸着部を一層安定して吸着でき、扉体の反りを矯正することができる。   In the closed position, when the moving body is arranged orthogonal to the door mounting portion or the mounting surface of the door body, the suction of the attracted portion by the permanent magnet is stabilized. Further, if the maximum projected area of the permanent magnet is formed larger than the maximum projected area of the moving body on the surface orthogonal to the insertion direction of the moving body with respect to the recess, the warp in the thickness direction of the door body tends to expand. Even when the door body is adjusted or the position of the door body is adjusted in the thickness direction (gap adjustment) with respect to the door mounting part, the permanent magnet can attract the attracted part more stably and correct the warping of the door body. be able to.

そして、案内部及び/又は移動体の縮径部は、扉体が開放位置から閉鎖位置に移行するとき、移動体の縮径部と案内部との当接により発生する音及び振動を緩衝する突出側緩衝材で覆われていることが好ましい。   The reduced diameter portion of the guide portion and / or the moving body buffers sound and vibration generated by the contact between the reduced diameter portion of the movable body and the guide portion when the door moves from the open position to the closed position. It is preferable that the projection-side cushioning material is covered.

移動体の突出により縮径部と案内部とが当接しても、突出側緩衝材によって不快な異音や振動の発生が抑制されるので、静かな環境下で扉体の反り矯正構造を作動させることができる。なお、突出側緩衝材には、高分子材料(例えば、シリコーン樹脂等の合成樹脂)を用いることができ、案内部や移動体の縮径部の表面に焼付けしてもよい。また、突出側緩衝材によって保持体の凹部表面を覆ってもよく、この場合には、移動体の縮径部が保持体の凹部に当接する際に発生する音や振動をも抑制することができる。   Even if the reduced-diameter part and the guide part come into contact with each other due to the protrusion of the moving body, the protruding cushioning material suppresses the generation of unpleasant noise and vibration, so the door body warp correction structure operates in a quiet environment. Can be made. In addition, a polymeric material (for example, synthetic resin, such as a silicone resin) can be used for the protrusion side buffer material, and you may bake on the surface of the reduced diameter part of a guide part or a moving body. In addition, the protrusion-side cushioning material may cover the concave portion surface of the holding body. In this case, the sound and vibration generated when the reduced diameter portion of the movable body abuts the concave portion of the holding body is also suppressed. it can.

さらに、移動体は、縮径部を扉取付部の開口側に突出する形態でケース体に収納されるとともに、
移動体の縮径部とは反対側の端面とその端面に対向するケース体の内面との間に、扉体が閉鎖位置から開放位置に移行するとき、移動体の端面とケース体の内面との当接により発生する音及び振動を緩衝する退入側緩衝材が配置されていることが好ましい。
Furthermore, the moving body is housed in the case body in a form in which the reduced diameter portion protrudes to the opening side of the door mounting portion,
When the door moves from the closed position to the open position between the end surface opposite to the reduced diameter portion of the moving body and the inner surface of the case body facing the end surface, the end surface of the moving body and the inner surface of the case body It is preferable that a retreat-side cushioning material that cushions the sound and vibration generated by the abutment is disposed.

移動体の退入(付勢手段による戻り)により移動体の端面とケース体の内面とが当接しても、退入側緩衝材によって不快な異音や振動の発生が抑制されるので、静かな環境下で扉体の反り矯正構造を作動解除させることができる。具体的には、移動体の縮径部とは反対側の端面及び/又はその端面に対向するケース体の内面は、扉体が閉鎖位置から開放位置に移行するとき、移動体の端面とケース体の内面との当接により発生する音及び振動を緩衝する退入側緩衝材で覆われていてもよい。このように、退入側緩衝材を移動体の端面やケース体の内面に貼り付けたり焼付けたりすることができる。なお、退入側緩衝材には、高分子材料(例えば、発泡性ウレタンゴム等のエラストマー)を用いることができる。   Even if the end surface of the moving body comes into contact with the inner surface of the case body due to the retreat of the moving body (return by the biasing means), the retraction side cushioning material suppresses the generation of unpleasant noise and vibration, so The warp correction structure of the door body can be deactivated in a difficult environment. Specifically, the end surface opposite to the diameter-reduced portion of the moving body and / or the inner surface of the case body facing the end surface are arranged such that the end surface of the moving body and the case when the door body moves from the closed position to the open position. It may be covered with a retreat-side cushioning material that cushions sound and vibration generated by contact with the inner surface of the body. In this way, the entry-side cushioning material can be attached or baked on the end surface of the moving body or the inner surface of the case body. In addition, a polymeric material (for example, elastomers, such as foaming urethane rubber) can be used for the entrance side buffer material.

そこで、上記課題を解決するために、本発明の扉ユニットは、
上記したような反り矯正構造と、
扉取付部と扉体との間には、それら扉取付部と扉体とを回動軸線周りに相対回転するとともに、回動軸線に直交する面において扉体を少なくともその厚さ方向に移動調整可能な位置調整機構を有する蝶番と、が備えられた扉ユニットであって、
扉体を閉鎖位置において正面視したとき、反り矯正構造と蝶番とは、扉体の開閉用ノブの取付辺と平行な対辺において、保持体の凹部への移動体(の先端部)の挿入方向が蝶番の回動軸線に交差(例えば直交)するように配置されることを特徴とする。
Then, in order to solve the said subject, the door unit of this invention is
The warp correction structure as described above,
Between the door mounting portion and the door body, the door mounting portion and the door body are relatively rotated around the rotation axis, and the door body is moved and adjusted at least in the thickness direction on a plane orthogonal to the rotation axis. A hinge unit having a possible position adjustment mechanism,
When the door body is viewed from the front in the closed position, the warp correction structure and the hinge are inserted in the opposite direction parallel to the mounting side of the door opening and closing knob, and the insertion direction of the movable body (the tip portion thereof) into the concave portion of the holding body Is arranged so as to cross (for example, orthogonally intersect) the rotation axis of the hinge.

このように、取付施工時等に蝶番の位置調整機構を操作して、扉取付部(例えば固定枠)に対して扉体(例えば開き戸)を厚さ方向に位置調整(隙間調整)した場合にも、永久磁石の吸着力により反りの矯正を安定して行える。しかも、扉体の開閉用ノブの取付辺と平行な対辺に反り矯正構造と蝶番とを配置し、保持体の凹部への移動体の挿入方向が蝶番の回動軸線に交差(例えば直交)する。これによって、反り矯正構造のうち、扉体に取り付けられる移動体(例えばシャフト)又は保持体(例えばケーシング)に関して、扉体の開閉に伴う旋回半径が相対的に小さくなるので、扉取付部に取り付けられる保持体又は移動体との位置合わせが容易となる。   In this way, when the position adjustment mechanism (gap adjustment) of the door body (for example, a hinged door) is adjusted in the thickness direction with respect to the door mounting portion (for example, the fixed frame) by operating the hinge position adjustment mechanism at the time of installation work, etc. However, it is possible to stably correct the warp by the attractive force of the permanent magnet. Moreover, a warp correction structure and a hinge are arranged on the opposite side parallel to the mounting side of the door opening / closing knob, and the insertion direction of the moving body into the concave portion of the holding body intersects (for example, orthogonal) with the rotation axis of the hinge. . As a result, in the warp correction structure, the moving body (for example, shaft) or the holding body (for example, casing) attached to the door body has a relatively small turning radius when the door body is opened and closed. Positioning with the holding body or moving body to be performed becomes easy.

あるいは、上記課題を解決するために、本発明の扉ユニットは、
上記したような反り矯正構造と、
扉取付部と扉体との間には、それら扉取付部と扉体とを回動軸線周りに相対回転するとともに、回動軸線に直交する面において扉体を少なくともその厚さ方向に移動調整可能な位置調整機構を有する蝶番と、
案内部を閉鎖位置における扉体の厚さ方向に移動調整可能な案内部調整機構と、が備えられた扉ユニットであって、
蝶番の位置調整機構により扉体をその厚さ方向に移動調整できるとともに、案内部調整機構により案内部を扉体の厚さ方向に移動調整できることを特徴とする。
Or in order to solve the said subject, the door unit of this invention is the following.
The warp correction structure as described above,
Between the door mounting portion and the door body, the door mounting portion and the door body are relatively rotated around the rotation axis, and the door body is moved and adjusted at least in the thickness direction on a plane orthogonal to the rotation axis. A hinge having a possible position adjustment mechanism;
A guide unit adjusting mechanism capable of moving and adjusting the guide unit in the thickness direction of the door body in the closed position;
The door body can be moved and adjusted in the thickness direction by the hinge position adjusting mechanism, and the guide part can be moved and adjusted in the thickness direction of the door body by the guide part adjusting mechanism.

このように、取付施工時等に蝶番の位置調整機構を操作して、扉取付部(例えば固定枠)に対して扉体(例えば開き戸)を厚さ方向に位置調整(隙間調整)した場合に、案内部調整機構を操作して、案内部を扉体の厚さ方向に移動調整できるので、永久磁石の吸着力により反りの矯正を広範囲に安定して行える。   In this way, when the position adjustment mechanism (gap adjustment) of the door body (for example, a hinged door) is adjusted in the thickness direction with respect to the door mounting portion (for example, the fixed frame) by operating the hinge position adjustment mechanism at the time of installation work, etc. Since the guide part can be moved and adjusted in the thickness direction of the door body by operating the guide part adjusting mechanism, the warp can be corrected stably over a wide range by the attractive force of the permanent magnet.

(実施例1)
以下、図面を参照しながら発明の実施の形態について説明する。図1は本発明に係る反り矯正構造を開き戸及び固定枠に取り付けた状態を示す正面図及び側面図、図2は反り矯正構造の取付状態を開き戸の開放位置にて示す斜視図、図3は反り矯正構造の取付状態の一例を開き戸の閉鎖位置にて示す平面断面図である。
Example 1
Hereinafter, embodiments of the invention will be described with reference to the drawings. FIG. 1 is a front view and a side view showing a state in which the warp correction structure according to the present invention is attached to a hinged door and a fixed frame, FIG. 2 is a perspective view showing an attachment state of the warp correction structure in an open position of the door, and FIG. It is a plane sectional view showing an example of the attachment state of a curvature correction structure in the closed position of a hinged door.

図1及び図2に示す扉ユニット1には、縦長矩形状の開口(部屋出入口)を構成する固定枠5(扉取付部)に対して開閉可能な開き戸2(扉体)の右下部に下側蝶番3(蝶番)が取り付けられ、その右上部に上側蝶番4(蝶番)が取り付けられている。具体的には、開き戸2の縦辺(長手辺)の中間部にドアノブ2c(開閉用ノブ)が取り付けられ、その縦辺と平行な対辺をなす木口2aと、開き戸2を閉めたとき木口2aに対向する固定枠5の縦枠5aとに跨って、各蝶番3,4は取り付けられている。このように、開き戸2は、ドアノブ2cの操作により、固定枠5の開口を閉鎖する閉鎖位置(図1)と開放する開放位置(図2)との間で、蝶番3,4の鉛直方向の回動軸線O1周りに開閉可能である。   The door unit 1 shown in FIG. 1 and FIG. 2 is provided at the lower right portion of a hinged door 2 (door body) that can be opened and closed with respect to a fixed frame 5 (door mounting portion) that constitutes a vertically long rectangular opening (room entrance). A side hinge 3 (hinge) is attached, and an upper hinge 4 (hinge) is attached to the upper right part thereof. Specifically, a door knob 2c (opening / closing knob) is attached to an intermediate portion of the vertical side (longitudinal side) of the hinged door 2, and a lip 2a that forms an opposite side parallel to the vertical side and the lip 2a when the hinged door 2 is closed. The hinges 3 and 4 are attached across the vertical frame 5a of the fixed frame 5 opposite to the frame 5a. Thus, the hinged door 2 is operated in the vertical direction of the hinges 3 and 4 between the closed position (FIG. 1) for closing the opening of the fixed frame 5 and the open position (FIG. 2) for opening the fixed frame 5 by the operation of the door knob 2c. It can be opened and closed around the rotation axis O1.

また、蝶番3,4は、閉鎖位置において、開き戸2と固定枠5との前後隙間S1、左右隙間S2及び上下隙間S3(図1参照)を微調整するために、開き戸2(部屋出入口)の内側から、開き戸2を厚さ方向X、幅方向Y及び高さ方向Zの3方向(図2参照)に各々位置調整可能な位置調整機構を備えている。ただし、X,Y,Z3方向へ開き戸2を移動させるための位置調整機構には、本願出願人が特許第3798416号公報(特許文献1)にて開示したものをそのまま採用しているので、ここでは詳細説明を省略する。なお、開き戸2(蝶番3,4)の回動軸線O1は高さ方向Zに沿って配置されている。   Further, the hinges 3 and 4 are arranged at the closed position of the hinged door 2 (room entrance) in order to finely adjust the front-rear gap S1, the left-right gap S2, and the vertical gap S3 (see FIG. 1) between the hinged door 2 and the fixed frame 5. A position adjustment mechanism is provided that can adjust the position of the hinged door 2 from the inside in three directions (thickness direction X, width direction Y, and height direction Z) (see FIG. 2). However, as the position adjustment mechanism for moving the hinged door 2 in the X, Y, Z3 directions, the one disclosed by the present applicant in Japanese Patent No. 3798416 (Patent Document 1) is employed as it is. Detailed description will be omitted. The rotation axis O1 of the hinged door 2 (hinges 3 and 4) is arranged along the height direction Z.

さらに、下側蝶番3と上側蝶番4との中間位置には、開き戸2の厚さ方向Xへの反りを矯正するための反り矯正構造6が、開き戸2の木口2aと固定枠5の縦枠5aとに跨って取り付けられている。この反り矯正構造6は、縦枠5aに埋め込まれた高分子材料(例えばポリアミド(PA)等の合成樹脂)製の磁石ケース10(保持体)と、木口2aに埋め込まれた金属(例えば亜鉛ダイキャスト)製又は高分子材料(例えばポリアミド(PA)等の合成樹脂)製のシャフトケース20(ケース体)とを備える。   Further, a warp correction structure 6 for correcting a warp in the thickness direction X of the hinged door 2 is provided at a middle position between the lower hinge 3 and the upper hinge 4. It is attached across 5a. The warp correction structure 6 includes a magnet case 10 (holding body) made of a polymer material (for example, a synthetic resin such as polyamide (PA)) embedded in a vertical frame 5a, and a metal (for example, a zinc die) embedded in a mouthpiece 2a. And a shaft case 20 (case body) made of a polymer material (for example, a synthetic resin such as polyamide (PA)).

図3に示すように、シャフトケース20は、開き戸2が開放位置(図8(a)参照)から閉鎖位置(図8(c)参照)に移行する際に木口2aから移動軸線O2(移動方向)に沿って突出移動し、閉鎖位置から開放位置に移行する際に木口2aへ移動軸線O2に沿って退入移動する鋼鉄(例えば圧延鋼材)製円柱形状(軸状)のシャフト22(移動体)を内蔵する。一方、磁石ケース10は、突出状態のシャフト22の先端部22aを挿入保持するための矩形状(例えば擬似正方形状;図5参照)の凹部10aを有する。また、磁石ケース10は、円盤状のネオジム磁石12(永久磁石)を内蔵しているので、シャフト22の先端部22aは、ネオジム磁石12の磁界から磁気誘導作用を受けて磁化することにより、ネオジム磁石12に吸着可能な被吸着部となる。開き戸2の開放位置において、シャフト22及びネオジム磁石12は、それぞれ開き戸2の木口2a及び固定枠5の縦枠5aから大きく飛び出さないため、安全性が高く見栄えもよい。なお、移動軸線O2(幅方向Y)は回動軸線O1(高さ方向Z)と直交している(図1(a)参照)。   As shown in FIG. 3, the shaft case 20 has a movement axis O2 (moving direction) from the lip 2a when the hinged door 2 moves from the open position (see FIG. 8A) to the closed position (see FIG. 8C). ) And a cylindrical (shaft) shaft 22 (moving body) made of steel (for example, rolled steel) that retreats along the movement axis O2 to the lip 2a when moving from the closed position to the open position. ). On the other hand, the magnet case 10 has a concave portion 10a having a rectangular shape (for example, a pseudo square shape; see FIG. 5) for inserting and holding the distal end portion 22a of the protruding shaft 22. Moreover, since the magnet case 10 contains the disk-shaped neodymium magnet 12 (permanent magnet), the front-end | tip part 22a of the shaft 22 receives a magnetic induction effect | action from the magnetic field of the neodymium magnet 12, and is magnetized. It becomes an attracted portion that can be attracted to the magnet 12. In the open position of the hinged door 2, the shaft 22 and the neodymium magnet 12 do not protrude greatly from the wooden mouth 2a of the hinged door 2 and the vertical frame 5a of the fixed frame 5, respectively, so that the safety is high and the appearance is good. The movement axis O2 (width direction Y) is orthogonal to the rotation axis O1 (height direction Z) (see FIG. 1A).

図4〜図7によりさらに具体的に説明する。図4は固定枠への磁石ケースの取付状態を示す平面断面図及び側面図、図5はその磁石ケースの分解斜視図、図6は開き戸へのシャフトケースの取付状態を示す平面半断面図及び側面図、図7はそのシャフトケースの分解斜視図である。   This will be described more specifically with reference to FIGS. 4 is a cross-sectional plan view and a side view showing the magnet case attached to the fixed frame, FIG. 5 is an exploded perspective view of the magnet case, and FIG. 6 is a half plan cross-sectional view showing the shaft case attached to the hinged door. FIG. 7 is an exploded perspective view of the shaft case.

図4及び図5に示すように、磁石ケース10には、縦枠5aに取り付けるための取付部10bの中央部に凹部10aが形成されており、取付部10bと一体成形された円筒形の収納部10cにネオジム磁石12が収納されている。磁石ケース10と同じ材料製の裏蓋13が、その係合爪13aを収納部10cに形成された係合孔10eに係合させることによって、磁石ケース10の後方側(縦枠5aへの埋め込み側)から被せられている。   As shown in FIGS. 4 and 5, the magnet case 10 has a concave portion 10a formed at the center of the mounting portion 10b for mounting to the vertical frame 5a, and a cylindrical storage integrally formed with the mounting portion 10b. The neodymium magnet 12 is accommodated in the part 10c. A back cover 13 made of the same material as that of the magnet case 10 engages the engagement claw 13a with an engagement hole 10e formed in the storage portion 10c, whereby the magnet case 10 is embedded in the rear side (embedded in the vertical frame 5a). From the side).

一方、磁石ケース10(取付部10b)の前方側には、金属(例えばステンレス)製の前板11(保持体)が配置されている。前板11には、その中央部において磁石ケース10の凹部10aに対応する形状の貫通孔11cが形成されている。また、前板11の周辺部(例えば高さ方向Zの2ヶ所)には、閉鎖位置における開き戸2の厚さ方向Xに長軸を有する長孔11d(案内部調整機構)が貫通形成され、この長孔11dに対応して磁石ケース10の取付部10bに貫通形成された取付孔10dとともに、ビス等の締結部材(図示せず)によって縦枠5aに共締め固定されている。長孔11dによって、前板11は縦枠5a及び磁石ケース10に対して厚さ方向Xに移動調整可能である。   On the other hand, a front plate 11 (holding body) made of metal (for example, stainless steel) is disposed on the front side of the magnet case 10 (mounting portion 10b). The front plate 11 is formed with a through hole 11c having a shape corresponding to the concave portion 10a of the magnet case 10 at the center thereof. In addition, a long hole 11d (guide portion adjusting mechanism) having a long axis in the thickness direction X of the hinged door 2 in the closed position is formed through the periphery of the front plate 11 (for example, two places in the height direction Z). Along with the mounting hole 10d formed through the mounting portion 10b of the magnet case 10 so as to correspond to the long hole 11d, it is fastened together with the vertical frame 5a by a fastening member (not shown) such as a screw. The front plate 11 can be moved and adjusted in the thickness direction X with respect to the vertical frame 5a and the magnet case 10 by the long hole 11d.

図6及び図7に示すように、シャフトケース20には、木口2aに取り付けるための取付部20bの中央部に、シャフト22(先端部22a)の移動軸線O2方向(長手方向)の移動(突出及び退入)を許容する挿通孔20aが貫通形成されており、取付部20bと一体成形された円筒形の収納部20cにシャフト22が収納されている。シャフトケース20と同じ材料製の裏蓋21(ケース体)が、その係合爪21aを収納部20cに形成された係合孔20eに係合させることによって、シャフトケース20の後方側(木口2aへの埋め込み側)から被せられている。なお、取付部20bの周辺部(例えば高さ方向Zの2ヶ所)には取付孔20dが貫通形成され、シャフトケース20はビス等の締結部材(図示せず)によって木口2aに固定されている。   As shown in FIGS. 6 and 7, the shaft case 20 is moved (protruded) in the movement axis O2 direction (longitudinal direction) of the shaft 22 (tip portion 22a) at the center portion of the attachment portion 20b for attachment to the end 2a. And an insertion hole 20a that allows retraction), and the shaft 22 is housed in a cylindrical housing portion 20c that is integrally formed with the mounting portion 20b. A back cover 21 (case body) made of the same material as that of the shaft case 20 engages the engagement claw 21a with an engagement hole 20e formed in the storage portion 20c, whereby the rear side (the end 2a of the shaft case 20). From the embedding side). In addition, mounting holes 20d are formed through the periphery of the mounting portion 20b (for example, two locations in the height direction Z), and the shaft case 20 is fixed to the pier 2a by a fastening member (not shown) such as a screw. .

また、シャフトケース20の取付部20bと、シャフト22の後端部に形成されたフランジ部22bとの間には、シャフト22(先端部22a)を常時退入状態に付勢するための圧縮コイルばね23(付勢手段)が介装されている。シャフト22は先端部22a(被吸着部)が先端に向かうにつれて連続的に縮径する縮径部(例えば、球面アール形状の面取り部)に構成されている。   Further, a compression coil for constantly urging the shaft 22 (front end portion 22a) in a retracted state between the mounting portion 20b of the shaft case 20 and a flange portion 22b formed at the rear end portion of the shaft 22. A spring 23 (biasing means) is interposed. The shaft 22 is configured as a reduced diameter portion (for example, a spherical rounded chamfered portion) whose diameter is continuously reduced as the distal end portion 22a (adsorbed portion) moves toward the distal end.

図4に戻り、前板11の貫通孔11cには、シャフト22の先端部22a(縮径部)を磁石ケース10の凹部10aに導入案内するために、前板11の一部を折り込む形で当接ガイド11a(案内部)が形成されている。具体的には、当接ガイド11aは、凹部10aに対するシャフト22の挿入方向(移動軸線O2方向)前方側(下手側)ほどシャフト22に近づく(移動軸線O2に漸近する)ように湾曲形成されている。したがって、当接ガイド11aは、シャフト22の先端部22aが当接したとき、シャフト22を挿入方向に引き寄せつつ磁石ケース10の凹部10aへ誘い込み案内する。一方、前板11の貫通孔11cにおいて、当接ガイド11aの対向辺から前板11の一部を折り込む形で対向ガイド11bが形成され、当接ガイド11aで誘い込み案内されたシャフト22の挿入方向を移動軸線O2方向に整える機能を有している。   Returning to FIG. 4, a part of the front plate 11 is folded into the through hole 11 c of the front plate 11 in order to introduce and guide the tip 22 a (reduced diameter portion) of the shaft 22 into the recess 10 a of the magnet case 10. A contact guide 11a (guide portion) is formed. Specifically, the abutment guide 11a is curvedly formed so as to approach the shaft 22 (asymptotically approach the movement axis O2) toward the front side (lower side) in the insertion direction (movement axis line O2 direction) of the shaft 22 with respect to the recess 10a. Yes. Therefore, when the tip 22a of the shaft 22 comes into contact, the contact guide 11a guides and guides the shaft 22 to the recess 10a of the magnet case 10 while pulling the shaft 22 in the insertion direction. On the other hand, in the through hole 11c of the front plate 11, the opposed guide 11b is formed by folding a part of the front plate 11 from the opposed side of the contact guide 11a, and the insertion direction of the shaft 22 guided and guided by the contact guide 11a. Has a function of adjusting the movement axis in the direction of the moving axis O2.

当接ガイド11aの両面は、高分子材料(例えば、シリコーン樹脂等の合成樹脂)製の緩衝片14(突出側緩衝材)で挟み込まれている。緩衝片14によって、当接ガイド11aとシャフト22の先端部22aとが当接する際に発生する音や振動が緩衝(軽減)される。この緩衝片14は、当接ガイド11aから先へ延びて磁石ケース10の凹部10aの表面(底面)を覆い、対向ガイド11bの折り曲げ先端付近まで達している。これによって、シャフト22の先端部22aが磁石ケース10の凹部10a表面に当接する際に発生する音や振動も緩衝(軽減)される。なお、緩衝片14の先端をさらに延ばして対向ガイド11bまで覆ってもよい。   Both surfaces of the contact guide 11a are sandwiched between buffer pieces 14 (projecting side buffer materials) made of a polymer material (for example, synthetic resin such as silicone resin). The buffer piece 14 buffers (reduces) sound and vibration generated when the contact guide 11a and the tip 22a of the shaft 22 contact each other. The buffer piece 14 extends from the contact guide 11a to cover the surface (bottom surface) of the concave portion 10a of the magnet case 10 and reaches the vicinity of the bent tip of the opposing guide 11b. Thereby, the sound and vibration generated when the tip 22a of the shaft 22 abuts against the surface of the recess 10a of the magnet case 10 are also buffered (reduced). Note that the tip of the buffer piece 14 may be further extended to cover the opposing guide 11b.

図7に戻り、シャフト22のフランジ部22bの後端面には、高分子材料(例えば、発泡性ウレタンゴム等のエラストマー)製の緩衝板24(退入側緩衝材)が貼り付けられている。緩衝板24によって、開き戸2が閉鎖位置(図8(c)参照)から開放位置(図8(a)参照)に移行するとき、圧縮コイルばね23の付勢力によるシャフト22の退入に伴って、フランジ部22bの後端面と裏蓋21の内面とが当接する際に発生する音や振動が緩衝(軽減)される。   Returning to FIG. 7, a buffer plate 24 (retraction side buffer material) made of a polymer material (for example, an elastomer such as foaming urethane rubber) is attached to the rear end surface of the flange portion 22 b of the shaft 22. When the hinged door 2 is moved from the closed position (see FIG. 8C) to the open position (see FIG. 8A) by the buffer plate 24, the shaft 22 is retracted by the biasing force of the compression coil spring 23. The sound and vibration generated when the rear end surface of the flange portion 22b and the inner surface of the back cover 21 come into contact with each other are buffered (reduced).

なお図4(a),(b)に表されているように、ネオジム磁石12の軸直交断面積(直径)はシャフト22の最大軸直交断面積(最大直径)よりも大きい。これによって、開き戸2の厚さ方向Xへの反りが拡大傾向になった場合や、開き戸2を厚さ方向Xに位置調整(前後隙間S1調整;図3参照)した場合にも、ネオジム磁石12がシャフト22の先端部22a(被吸着部)を安定して吸着でき、開き戸2の反りを矯正することができる。また、開き戸2の厚さ方向Xへの位置調整量(前後隙間S1調整量)が大きい場合には、長孔11dによって前板11を厚さ方向Xに移動調整すれば、シャフト22の先端部22aと当接ガイド11aとの当接開始位置(誘い込み開始位置)を調節することができる。   4A and 4B, the neodymium magnet 12 has an axial cross-sectional area (diameter) larger than the maximum axial orthogonal cross-sectional area (maximum diameter) of the shaft 22. As a result, the neodymium magnet 12 can also be used when the warpage of the hinged door 2 in the thickness direction X tends to expand, or when the hinged door 2 is adjusted in position in the thickness direction X (adjustment of the front and rear gap S1; see FIG. 3). However, the front-end | tip part 22a (to-be-adsorbed part) of the shaft 22 can be adsorb | sucked stably, and the curvature of the hinged door 2 can be corrected. Further, when the position adjustment amount (the front-rear gap S1 adjustment amount) in the thickness direction X of the hinged door 2 is large, if the front plate 11 is moved and adjusted in the thickness direction X by the long hole 11d, the distal end portion of the shaft 22 The contact start position (leading start position) between 22a and the contact guide 11a can be adjusted.

次に、図8を用いて、以上のような反り矯正構造6の作動状況を説明する。
(1)開き戸2が開放位置(図8(a))から閉鎖位置(図8(c))に移行するとき;
シャフト22の先端部22aは、ネオジム磁石12との接近につれてネオジム磁石12による磁気誘導作用の度合いが強まることによって、ネオジム磁石12への吸着力が圧縮コイルばね23の付勢力を上回り、ネオジム磁石12に吸着されて、シャフトケース20の挿通孔20aから突出する。その際、図8(b)に示す誘い込み開始位置に達すると、シャフト22の先端部22aが当接ガイド11a(実際には緩衝片14)に当接する。シャフト22は、挿入方向(移動軸線O2方向)に引き寄せられつつ磁石ケース10の凹部10aへ誘い込み案内され、対向ガイド11bとの間に挿入保持されて、反り矯正構造6が作動(開き戸2の厚さ方向Xへの反りを矯正)する。なお、誘い込み開始位置(図8(b))から開き戸閉鎖位置(図8(c))に至る間では、シャフト22は磁石ケース10の凹部10aの底面(緩衝片14の延長部)で押し戻されてシャフトケース20の挿通孔20aへ若干退入し、それにつれて圧縮コイルばね23も若干伸びる。
Next, the operation state of the warp correction structure 6 as described above will be described with reference to FIG.
(1) When the hinged door 2 moves from the open position (FIG. 8 (a)) to the closed position (FIG. 8 (c));
The tip portion 22 a of the shaft 22 increases the degree of magnetic induction by the neodymium magnet 12 as it approaches the neodymium magnet 12, so that the attracting force to the neodymium magnet 12 exceeds the urging force of the compression coil spring 23, and the neodymium magnet 12. To protrude from the insertion hole 20a of the shaft case 20. At that time, when the leading start position shown in FIG. 8B is reached, the tip 22a of the shaft 22 comes into contact with the contact guide 11a (actually the buffer piece 14). The shaft 22 is drawn and guided to the concave portion 10a of the magnet case 10 while being drawn in the insertion direction (moving axis O2 direction), inserted and held between the opposing guides 11b, and the warp correction structure 6 operates (the thickness of the hinged door 2). To correct warping in the direction X). The shaft 22 is pushed back by the bottom surface of the recess 10a of the magnet case 10 (extension portion of the buffer piece 14) between the leading start position (FIG. 8B) and the hinged door closing position (FIG. 8C). As a result, the compression coil spring 23 is slightly extended.

(2)開き戸2が閉鎖位置(図8(c))から開放位置(図8(a))に移行するとき;
シャフト22の先端部22aは、ネオジム磁石12からの離間につれてネオジム磁石12による磁気誘導作用の度合いが弱まることによって、ネオジム磁石12への吸着力が圧縮コイルばね23の付勢力を下回り、ネオジム磁石12から離反して、シャフトケース20の挿通孔20aへ退入する。その際、図8(b)に示す誘い込み終了位置に達すると、シャフト22の先端部22aが当接ガイド11a(実際には緩衝片14)から離反し、反り矯正構造6の作動(開き戸2の厚さ方向Xへの反り矯正)が解除される。なお、開き戸閉鎖位置(図8(c))から誘い込み終了位置(図8(b))に至る間では、シャフト22はシャフトケース20の挿通孔20aから若干突出し、それにつれて圧縮コイルばね23も若干縮む。
(2) When the hinged door 2 moves from the closed position (FIG. 8C) to the open position (FIG. 8A);
Since the degree of magnetic induction by the neodymium magnet 12 decreases as the tip 22 a of the shaft 22 moves away from the neodymium magnet 12, the attractive force to the neodymium magnet 12 is less than the biasing force of the compression coil spring 23, and the neodymium magnet 12. In this case, the shaft case 20 retreats from the insertion hole 20a. At this time, when reaching the end position for guiding shown in FIG. 8 (b), the tip 22a of the shaft 22 is separated from the contact guide 11a (actually, the buffer piece 14), and the operation of the warp correction structure 6 (the door 2) (Warp correction in the thickness direction X) is released. The shaft 22 slightly protrudes from the insertion hole 20a of the shaft case 20 between the hinged door closed position (FIG. 8C) and the lead-in end position (FIG. 8B), and the compression coil spring 23 slightly increases accordingly. Shrink.

このように、開き戸2の閉鎖位置への移動(回動)毎にネオジム磁石12がシャフト22を突出させてその先端部22a(被吸着部)を吸着するので、使用に伴って開き戸2の厚さ方向Xへの反りが拡大傾向になっても、ネオジム磁石12の吸着力により反りの矯正を安定して行える。また、取付施工時等に、固定枠5に対して開き戸2を厚さ方向Xや幅方向Yに位置調整(隙間調整)した場合にも、ネオジム磁石12の吸着力により反りの矯正を安定して行える。その際、開き戸2の幅方向Y位置(左右隙間S2)の変更(調整)に対して、誘い込み開始位置から開き戸閉鎖位置に至る間でのシャフト22の戻り(退入)量が反り矯正構造6の調整代として機能する。一方、開き戸2の厚さ方向X位置(前後隙間S1)の変更(調整)に対して、当接ガイド11a(緩衝片14)での誘い込み作用が反り矯正機能を維持する役割を担うとともに、長孔11dによる誘い込み開始位置の調節量が反り矯正構造6の調整代として機能する。しかも、開き戸2の閉・開操作に応じてネオジム磁石12によりシャフト22を移動させるだけで反り矯正構造6の作動・作動解除の切換が行えるので、反り矯正機能を長期間にわたり安定して発揮することができる。   Thus, every time the hinged door 2 moves (rotates) to the closed position, the neodymium magnet 12 causes the shaft 22 to protrude and attract the tip 22a (adsorbed portion). Even when the warpage in the direction X tends to expand, the correction of the warp can be stably performed by the attractive force of the neodymium magnet 12. In addition, when the hinged door 2 is adjusted in position in the thickness direction X or width direction Y (gap adjustment) with respect to the fixed frame 5 at the time of installation or the like, the correction of the warp is stabilized by the attractive force of the neodymium magnet 12. Can be done. At that time, with respect to the change (adjustment) of the width direction Y position (left and right gap S2) of the hinged door 2, the return (retreat) amount of the shaft 22 from the leading start position to the hinged door closed position is the warpage correction structure 6. Functions as an adjustment fee. On the other hand, with respect to the change (adjustment) of the thickness direction X position (front-rear gap S1) of the hinged door 2, the guiding action in the contact guide 11a (buffer piece 14) plays a role of maintaining the warp correction function and is long. The adjustment amount of the leading start position by the hole 11d functions as an adjustment allowance for the warp correction structure 6. Moreover, since the operation / deactivation of the warp correction structure 6 can be switched simply by moving the shaft 22 by the neodymium magnet 12 according to the closing / opening operation of the hinged door 2, the warp correction function can be stably exhibited over a long period of time. be able to.

(変形例)
図9にシャフトの変形例を示す。図9に示すシャフト22(移動体)では、その先端部22a(被吸着部)に補助ネオジム磁石22’(補助永久磁石)を埋め込んで、先端部22aをかしめてある。補助ネオジム磁石22’とネオジム磁石12(図3参照)とは、開き戸2の閉鎖位置において互いに対向することとなる対向部位での極性を異ならせてある(例えば、ネオジム磁石12が+極で補助ネオジム磁石22’が−極)ので、両磁石12,22’間の磁気作用に基づき吸着力が増大する。
(Modification)
FIG. 9 shows a modification of the shaft. In the shaft 22 (moving body) shown in FIG. 9, an auxiliary neodymium magnet 22 ′ (auxiliary permanent magnet) is embedded in the tip portion 22a (attracted portion), and the tip portion 22a is caulked. The auxiliary neodymium magnet 22 ′ and the neodymium magnet 12 (see FIG. 3) have different polarities at opposing portions that face each other at the closed position of the hinged door 2 (for example, the neodymium magnet 12 is supplemented by a positive pole). Since the neodymium magnet 22 'is a negative pole), the attractive force increases based on the magnetic action between the two magnets 12, 22'.

この場合、シャフト22には、ネオジム磁石12の磁気誘導作用に基づくネオジム磁石12とシャフト22の先端部22a(被吸着部)との間の吸着力に加えて、ネオジム磁石12と補助ネオジム磁石22’との間の磁気作用に基づく吸着力が作用することになり、シャフト22(先端部22a)が円滑にかつ安定して突出移動する。   In this case, the shaft 22 includes the neodymium magnet 12 and the auxiliary neodymium magnet 22 in addition to the attractive force between the neodymium magnet 12 based on the magnetic induction effect of the neodymium magnet 12 and the tip 22a (adsorbed portion) of the shaft 22. The attraction force based on the magnetic action between “and” acts, and the shaft 22 (tip portion 22a) protrudes and moves smoothly and stably.

(実施例2)
図10は反り矯正構造の取付状態の他の例を開き戸の閉鎖位置にて示す平面断面図である。図10に示す反り矯正構造106では、固定枠5(扉取付部)の縦枠5aにシャフト22(移動体)を取り付け、開き戸2(扉体)の木口2aに磁石ケース10(保持体)を固定している。図10の反り矯正構造106においても、シャフト22の先端部22aが、ネオジム磁石12(永久磁石)の磁界から磁気誘導作用を受けて磁化することにより、ネオジム磁石12に吸着可能な被吸着部となることに変わりはない。また、当接ガイド11aが、凹部10aに対するシャフト22の挿入方向(移動軸線O2方向)前方側(下手側)ほどシャフト22に近づく(移動軸線O2に漸近する)ように湾曲形成されていることも実施例1(図4(a)参照)と同様である。ただし、緩衝板24(退入側緩衝材)は、裏蓋21(ケース体)の内面に貼り付けられている。
(Example 2)
FIG. 10 is a plan cross-sectional view showing another example of the attached state of the warp correction structure at the closed position of the hinged door. In the warp correction structure 106 shown in FIG. 10, the shaft 22 (moving body) is attached to the vertical frame 5 a of the fixed frame 5 (door attachment portion), and the magnet case 10 (holding body) is attached to the mouth 2 a of the hinged door 2 (door body). It is fixed. Also in the warp correction structure 106 in FIG. 10, the tip portion 22 a of the shaft 22 is magnetized by receiving a magnetic induction effect from the magnetic field of the neodymium magnet 12 (permanent magnet), thereby attracting the attracted portion that can be attracted to the neodymium magnet 12. There will be no change. In addition, the contact guide 11a may be curved so as to be closer to the shaft 22 (asymptotically closer to the movement axis O2) toward the front side (lower side) in the insertion direction (movement axis O2 direction) of the shaft 22 with respect to the recess 10a. This is the same as Example 1 (see FIG. 4A). However, the buffer plate 24 (retraction side buffer material) is affixed to the inner surface of the back cover 21 (case body).

なお、変形例(図9)及び実施例2(図10)において実施例1(図3〜図8)と共通する機能を有する部分にはそれぞれ同一符号を付して説明を省略する。   In the modification (FIG. 9) and the second embodiment (FIG. 10), parts having the same functions as those in the first embodiment (FIGS. 3 to 8) are denoted by the same reference numerals, and the description thereof is omitted.

以上の実施例では開き戸2(蝶番3,4)の回動軸線O1が上下方向(鉛直方向)に位置する場合のみについて説明したが、本発明は回動軸線O1がその他の方向(例えば水平方向)に配置された反り矯正構造や扉ユニットにも適用される。また、開き戸2の3方向の位置調整(隙間調整)は、開き戸2が固定枠5を閉鎖する状態で、開口(部屋出入口)の外側から行なうようにしてもよい。さらに、開き戸2において、ドアノブ2cと、蝶番3,4及び反り矯正構造6,106との左右位置関係を逆にしてもよい。なお、シャフト22を常時退入状態に付勢する圧縮コイルばね23に代わって、シャフト22の突出・退入移動に応じて流体を移動させて各々の状態を保持する機構(例えばガススプリング等の流体ばね)が用いられる場合がある。   In the above embodiment, only the case where the rotation axis O1 of the hinged door 2 (hinges 3 and 4) is positioned in the vertical direction (vertical direction) has been described. However, in the present invention, the rotation axis O1 is in another direction (for example, horizontal direction). It is also applied to the warp correction structure and door unit arranged in). Further, the position adjustment (gap adjustment) of the hinged door 2 in the three directions may be performed from the outside of the opening (room entrance) with the hinged door 2 closing the fixed frame 5. Furthermore, in the hinged door 2, the left-right positional relationship between the door knob 2c, the hinges 3, 4 and the warp correction structures 6, 106 may be reversed. Instead of the compression coil spring 23 that constantly biases the shaft 22 in the retracted state, a mechanism that moves the fluid in accordance with the protruding / retracting movement of the shaft 22 and maintains each state (for example, a gas spring or the like). Fluid spring) may be used.
